收藏资源简介:
ST-Evidence是一个用于评估视频理解中时空证据生成的综合基准数据集。它包含两个任务:生成任务(Gen)和多项选择题任务(MCQ)。数据集包含约1,300个6fps的视频,带有问题-答案对的时间段和空间掩码注释。视频内容涵盖多个领域。生成任务需要根据视频内容生成答案和时空证据,而多项选择题任务则需要从给定选项中选择正确答案。数据集提供了详细的评估指标,包括QA准确率、时间IoU/IoP和空间质量等。
ST-Evidence is a comprehensive benchmark dataset for evaluating spatio-temporal evidence generation in video understanding. It encompasses two distinct tasks: the generation task (Gen) and the multiple-choice question (MCQ) task. The dataset comprises approximately 1,300 6fps videos, annotated with temporal segments of question-answer pairs and spatial masks. The videos span a wide range of domains. The generation task requires generating corresponding answers and spatio-temporal evidence based on the video content, whereas the MCQ task demands selecting the correct answer from the provided candidate options. The dataset provides detailed evaluation metrics, including QA accuracy, temporal IoU/IoP, spatial quality, and so on.
